AXLE-LU BRICATO R.

SPECIFICATION forming part of Letters Patent No. 475,051, dated May 1'7, 1892.

Application filed January 6, 1892. Serial No. 417,221. (No model.

To aZZ whom it may concern.-

Be it known that I, GEORGE W. BEAL, a citizen of the United States of America, residing at Highlands, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Axle-Lubricators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompany- In the drawings is illustrated an embodi-- ment of the invention.

Figure 1 is a top or plan view of the extremity of the axle provided with my improved lubricator. Fig. 2 is a longitudinal section of the same. section of a tube and sleeve located within the axle and communicating with the oil-cup, reservoir, or supply source. Fig. 4. is a similar view showing the tube so adjusted as to allow the oil to escape therefrom through the opening in the sleeve to the journal or spindle. Fig. 5 is a fragmentary section of one extremity of the axle, showing the hub in place and the shield in position. Fig. 6 is a vertical transverse section taken on line a: m, Fig. 4. Fig. 7 is a top or plan view in detail of the shield secured to the axle and overlapping the hub to prevent sand or dirt passing to the journal.

Similar reference-characters representing corresponding parts or elements in the several views, let the numeral 5 designate the axle, 6 the spindle, and 7 the hub of the wheel.

Formed or located in the axle just beyond the spindle is an oil cup or receptacle 8, provided with a suitable opening at the top,

Fig. 3 is a longitudinal through which protrudes a small tube 9, to the upper extremity of which is secured a small plate 10, of sufficient size to normally cover the opening in the top of the reservoir. To the upper extremity of the tube above plate 10 is secured a button or slightly-enlarged top piece 12. The inner extremity of tube 9 occupies a vertical position within the oil-cup and may be moved outwardly therein by virtue of the elongated opening in the top of the reservoir or cup. At the bottom of the oil-cup tube 9 is formed into an elbow. From this point one arm 9 of the elbow extends through a suitable groove formed therefor nearly to the outer extremity of the spindle, the groove in which the tube lies being located just beneath the outer surface of the bearing. WVithin this groove is located a sleeve 13, provided with openings 14. The inner extremity of the sleeve is open, while its outer extremity is closed and provided with a coil-spring 15, which engages the outer extremity of arm 9 of the tube, which is chiefly located within this sleeve and provided with openings 16, which are normally closed by the sleeve, since the tube is forced inward by the spring 15, so that its openings do not coincide with the openings 14 in the sleeve.

Just outside of the bend in tube 9, within part 9 thereof and lying within the oil-cup, is formed an elongated opening 17, through which the oil or other lubricant passes to the tube. When it is desired to oil the axle bearing or spindle, it is only necessary to press outward on button or projection 12 and force the oil-tube to the position shown by dotted lines in Fig. 2. This outward oradjusted position of the tube is also shown in Fig. 4. The opening in the top of the oil-cup is just long enough to permit the tube to move outward to the adjusted position shown, or so that the openings 16 shall lie just beneath openings 14., allowing the oil to pass upward therethrough and thence to the journal through openings 18, formed in the spindle just above openings 14 of the sleeve and communicating therewith.

Rigidly secured to arm 9 of the tube are short projections 19, which extend upward through openings 14 and 18. These projections are adapted to clear these openings and openings inthe sleeve and spindle,projection 19 is moved the full length of the opening through which it passes, thus leaving the way; clear for the lubricant to pass from the tube therethrough as soon as openings 16 are moved into line. It will thus be seen that. projece tions 19 are located outward on the tube from the openings 16, suflicient space-being left between the projections and these openings to effectually seal the tube or prevent the passage of the lubricant therefrom when the tube is inits normal ,posi.tion,;or that shown -Fig, 3r

InFigs. 5,

vided interiorly with a rib or head 21, composed of rubber. or other resilient material adaptedto engage the hub andprevent dirt from passing. thereunder to the shoulder on the axle andthence tozthe journal. This shield or protector is only required'on heavy; or draftv wagons. I-Ience my improved lubri--: cator may beused .withor without the pro-; tector, as ,may be desired or preferable. When the shield is employed, the tube9 projects:

through a, suitableslot formed therein, which is of suf'ficientlength to permit said tube-the requiredmovement. In this casethe button 12 lies outside of the shield, so that the vehicle may-be oiled .without removing the same.

From theforegoing descriptionit will be observed that m y improved lubricator is not designed to. be automatic, since the oil only passes to the journal when the oil-tube is adjusted. It'will. also be seenthatby the use of my improvement the trouble and-annoyance'of removing, the Wheels of the Vehicle when it is desired to oil the same .is entirely done away with, it being onlyv necessary to force button;12 outward, when the lubricant will rise. through the openings 16, 14, and 18 to, the bearing, since the oil-receptacle is located above-the journal. .As soon as the oiltube-isvreleased the spring in the end of the sleeve ,returns 1 it to itsnormal position and immediately outs on. the flowof oil from the cup, or reservoir.

Having thus described my invention, Wh at I claim is,,.

1. In a lubricator, the combination, with the axle and the spindle, of an oil-cup formed or located within the axle in proximity to the spindle, an apertured oil tube or conduit lead- 6, and-,7 is illustrated a shieldor protector 20, secured to the axle and project-- ing oven the hub to prevent the sand and dirt; from passingtothe journal between the i-n ner extremity. of the hub and the shoulderv formed on the axle adjacent to the spindle.= The outer extremityof this shield is made to conform to theshape of the hub, and is proing from said cup to the spindle, which is provided with a longitudinal opening for its reception, the spindle being further provided with openings leading fromsaid longitudinal opening to the surface of the journal, a spring normally retaining the oil-tube in such a position that its apertures shall lie to one side of the openings in the spindle leading to the journal-bearing, and means connected with the tube, whereby the same may be adjusted from the outside of the axle to allow the lubricant to flow to the journal, substantially as described.
